[juampavaren]

Hi friends actually I work with Vector displacement map in Maya, I was try to do the sea waves like the tutorial section in the documentation like ever do it the VDM, in this case I use the Mac download from Arnold web page and rendering the scene and not working fine, I try to rendering in the same scene with another maps and working fine all except the waves map, I send you a image reference, I try to change all parameters in Arnold and nothing working, the render appear the the up and down part of the vector in flat form, thank you for your time and have a great weekend

Bad Map rendering: Wrong

Rendering the same scene with another maps: Good
